本教材是国内地下水流数值模拟的一本双语教材，内容包括基本理论、Visual MODFLOW软件使用和实践应用三部分，知识点系统全面。第一部分是地下水流数值模拟的基础理论，讲述了有关基本概念、基本定律、基本微分方程、数学模型的建立和有限差分方法等。第二部分讲述了Visual MODFLOW软件的使用步骤，包括水流模型的输入、运行和输出。第三部分为基于Visual MODFLOW软件的地下水流数值模拟应用实例，包括地下水库截渗墙建设的数值模拟和水源地保护区划分的数值模拟。

编者根据多年的教学经验和水文与水资源工程专业本科生双语课程“Numerical Simulation of Groundwater Flow”的教学示范总结，并融合了基本的水文地质学基础知识和地下水动力学理论，既注重强化学生的基础理论，又侧重培养学生的动手能力，教材特色鲜明，可作为高等院校水文与水资源工程、地下水科学与工程、市政工程和环境工程等相关专业本科生和研究生的教材。

<i>This bilingual textbook about numerical simulation of groundwater flow</i>，<i>can be divided into three parts including basic theory</i>，<i>Visual MODFLOW software introduction and practical application</i>.<i>The first part describes the basic concepts</i>，<i>fundamental law</i>，<i>basic differential equations</i>，<i>establishment of mathematical model and the finite-difference method</i>.<i>The second part presents the tutorial of Visual MODFLOW software</i>，<i>including the input</i>，<i>run and output of groundwater flow model</i>.<i>Based on Visual MODFLOW software</i>，<i>the numerical simulations of groundwater flow application case are recommended in the third part</i>，<i>including numerical simulation of impervious wall construction and protection zones delineation</i>.

<i>On the basis of many years of teaching experience and summary of bilingual teaching on</i>“<i>NUMERICAL SIMULATION OF GROUNDWATER FLOW</i>”<i>which is setting for Hydrology and Water Resources Engineering specialty</i>，<i>we have integrated basic hydrogeology knowledge and groundwater dynamics theory in the book</i>.<i>This distinctive textbook focuses on not only strengthening basic theory of hydrogeology but also cultivating students</i>’<i>practical ability</i>.<i>So this bilingual textbook can be used by undergraduates and graduates who are major in Hydrology and Water Resources Engineering</i>，<i>Groundwater Science and Engineering</i>，<i>Municipal Engineering and Environmental Engineering</i>.
